Unitech L-Malic Acid UniTab Enzymatic Test Kit

Unitech L-Malic Acid UniTab Enzymatic Test Kit is used for the determination of L-malic acid in grape juice, fermenting wine, and other samples. L-malic acid is present in grapes, apples, and other fruits and vegetables. In grape juice, its concentration drops from as high as 8 to 1g/L as the ripening process proceeds. L-Malic levels, along with sugar concentration, are typically used to gauge ripeness for wine production. Up to 30% of the malic acid may be consumed by yeast fermentation. A secondary fermentation is typical in wine.

Each kit contains enzymes, substrates, and buffer components in tablet form and as aqueous solutions and suspensions. Each reagent tablet is dissolved in 5mL of Malic Acid Buffer, permitting the user to prepare only as much working reagent as required for daily use. One drop of Trigger (start enzymes, Malate Dehydrogenase and GOT, reagent is sufficient to initiate the reaction) reagent is sufficient to initiate the reaction.
